How studies reach it

Disciplines it reaches
Solid: published studies. Light: examples.
Computed from the records on this site: what each study, template and specialist names as used, which study extends which, and who authored what. 19 studies in total.
What is in it
Confirmed exoplanets (more than 6,000) with orbital period, radius, mass, equilibrium temperature, discovery method/year/facility and host-star properties (temperature, radius, mass, metallicity, distance), from the NASA Exoplanet Archive. Good for radius–period and mass–radius distributions, discovery-method selection effects, planet properties by host-star type. Keyless; ADQL queries for anything else.
In e2er's words, from the source's definition.
Terms of use for the data
- Free and keyless; no licence is stated on the archive's pages.
- Acknowledge the archive with NASA's standard sentence and cite Christiansen et al. (2025).
- Cite the table's DOI (10.26133/NEA13 for pscomppars, 10.26133/NEA12 for ps).
- Cite the paper behind any single planet's values you rely on (the *_reflink columns).

The terms as e2er records them
No licence stated. The acknowledgement page (https://exoplanetarchive.ipac.caltech.edu/docs/acknowledge.html) asks: "Please include the following standard acknowledgment in any published material that makes use of the NASA Exoplanet Archive's services. This research has made use of the NASA Exoplanet Archive, which is operated by the California Institute of Technology, under contract with the National Aeronautics and Space Administration under the Exoplanet Exploration Program." and "if you use data from a specific literature reference, please acknowledge that reference directly", and to "cite Christiansen et al. (2025)". The TAP page (https://exoplanetarchive.ipac.caltech.edu/docs/TAP/usingTAP.html) asks: "If you use any of the following data sets for your research, please cite the archive's DOI for the data."

Technical details
Code in e2er: src/modules/data/sources/exoplanets.py
- e2er-data exoplanets planets: Confirmed planets, one row each, e.g. --since 2014 --method Transit --columns pl_name,pl_rade,pl_orbper --where 'pl_rade < 4'.
- e2er-data exoplanets query: Any ADQL SELECT on the archive's TAP tables (ps, pscomppars, stellarhosts, toi, k2pandc, …), e.g. --adql "select hostname, count(*) as n from pscomppars group by hostname".
